Portable Oxygen Monitor Introduction
Teledyne Analytical Instruments

The Class R17MED oxygen sensor is a disposable sensor. The sen-
sor has a cathode (sensing electrode), an anode (counter electrode), and
a compatible electrolyte, and is packaged in a small plastic sensor body.
Oxygen entering the sensor reacts with the anode and a proportional cur-
rent is collected at the cathode, which is then converted into a digital
signal and displayed on the LCD screen on the Monitor.
Used with the R17MED sensor is a removable plastic diverter. This
diverter is used to facilitate the transport of gas mixtures through the
sensor. The diverter, packaged separately when shipped, is necessary
when the tee adapter is used to sample gas flowing through a tube.
The diverter is not necessary and should not be used when the sen-
sor is placed directly in a chamber, or when the sensor is used in con-
fined volume analysis, such as incubators and inhalation tents.
The audio alarm is used for both the concentration alarms and the
sensor-disconnect alarm. The user can manually bypass the concentra-
tion alarm for a set amount of time. Pressing the ALARM SILENCE
() key will provide an audible alarm override for 115 seconds. After
that, if the alarm condition still prevails, the audible alarm will resume.
The ALARM SILENCE () key can also be used to interrupt the sen-
sor-disconnect audible alarm.
CAUTION STATEMENTS:
THE R17MED SENSOR CONTAINS A CAUSTIC ELECTRO-
LYTE AND LEAD. DO NOT TRY TO OPEN THE SENSOR
ASSEMBLY. CHECK THE SENSOR PERIODICALLY FOR
LEAKS. IF THE SENSOR IS LEAKING, REPLACE IT. DO
NOT TRY TO REPAIR IT. CONTACT YOUR DISTRIBUTOR
OR TELEDYNE FOR THE MATERIAL SAFETY DATA SHEET
RELATED TO HANDLING AND DISPOSAL OF THE SEN-
SOR.
THE R17MED SENSOR CONTAINS A CAUSTIC ELECTRO-
LYTE, AND IN THE EVENT OF A LEAK, THE ELECTROLYTE
MAY ATTACK CERTAIN MATERIALS IT IS EXPOSED TO,
SUCH AS ALUMINUM. USE PRECAUTION IN YOUR
CHOICE OF INTERFACE MATERIALS.
REMOVE AND SAVE THE DIVERTER WHEN THE SENSOR
IS USED IN CONFINED VOLUME APPLICATIONS.
